Mechanisms of regulation of cardiac rhythm have many individual features, which are conditioned by age, sex, training of the organism, strength and nature of external influence, constitutional features of the organism. The purpose of the work is to determine the relationship between cardiointervalographic indices and parameters of the external structure of the body in highly skilled wrestlers of the mesomorphic somatotype. The study involved 24 wrestlers between the ages of 17 and 21 with a high level of sportsmanship and more than 3 years of experience. All of the wrestlers were of medium weight and engaged in free and Greco-Roman wrestling. We conducted a study of heart rate variability on the cardiac computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association (1996). The indices of vegetative homeostasis according to Bayevsky, variational heart rate, statistical and spectral cardiointervalographic indicators were determined. Anthropometry was performed according to the method of V.V. Bunak (1941), somatotypological study – by the calculated modification of the Heath-Carter method (1990), determination of the component composition of body weight by the method of Matejko (1992). In the package “STATISTICA 5.5” correlation analysis was performed using the nonparametric Spearman statistical method. It was found that in the wrestlers of the mesomorphic somatotype, the variations of the pulsometry had the highest number and strength of reliable correlations with constitutional parameters, most of which were inverse of the mean force. All statistical indicators of heart rate variability with indicators of the external structure of the body had only inverse significant correlations. The least significant correlations were found for spectral indices and parameters of vegetative homeostasis. According to the results of the correlation analysis in the wrestlers of the mesomorphic somatotype, we can assume that with the increase of total, longitudinal, circumferential, transverse body sizes and muscle and bone mass, the variability of the heart rhythm of the sympathetic department of the autonomic nervous system will be more pronounced.

The features of tolerance to acute hypoxia by individuals with different levels of trait anxiety are presented. It was established that changes in such physiological parameters as heart rate in individuals with a high level of personal anxiety are more pronounced in hypoxic conditions. In particular, in this group, by the 25th minute of lifting in the altitude training chamber to a height of 5000 m, the heart rate increased by an average of 38.1% (p<0,01) of background values. In persons with a low level of trait anxiety, an increase in heart rate does not exceed an average 32% (p<0,01). However, in subjects with a high level of trait anxiety, compared with people with a low level of trait anxiety, a more pronounced increase in the Rufie index at an average of 18,2% (p<0,01). In addition, in individuals with a high level of trait anxiety, a more pronounced slowing-down time of a complex sensorimotor reaction by 33,0 ms (p<0,05) from the background value was observed, while in people with a low level of trait anxiety, on average, only by 20,2 ms (p<0,05). Thus, changes in individual physiological parameters in individuals with a high level of trait anxiety are more pronounced, their functional state is less tolerant to the hypoxia effect, and the level of physical performance is lower on average in this group.

To evaluate the ship-handling skills andkanseiof professionals and students, we studied physical performance and mental workload using a simulator and an actual ship. We demonstrated the effects of physiological indices based on professional performance and features as seen from their mental workload with heart rate variability, nasal temperature, and salivary amylase activity, and considered new practical education using professionalkansei.

Opuntia ficus indica (OFI) has many physiological effects, but a relationship between OFI and heart-rate variability (HRV) has never been established. The aim of this study was to describe the effects of a diet supplement of OFI on HRV in athletes. The first day, heart rate (HR) was measured at rest in supine (SU) and standing (ST) positions to analyze HRV in 10 athletes, followed by a randomized assignment to an OFI (5) or placebo (5) group. The next day, the athletes repeated the HRV test. One month later the crossover protocol was applied. In OFI, the high-frequency-activity HFSU (1,773 ± 2,927 vs. 5,856 ± 8,326 ms2, p < .05), HFST (295 ± 313 vs. 560 ± 515 ms2, p < .05), and low-frequency LFSU (1,621 ± 1,795 vs. 6,029 ± 9,007 ms2, p < .01) increased. HRSU (66 ± 13 vs. 57 ± 11 beats/min, p < .01) and HRST (87 ± 11 vs. 76 ± 9 beats/min, p < .01) decreased. A diet supplement of OFI increases HF and LF activities and decreases HR.

Objective: to analyze the correlations of the parameters of heart rate variability (HRV) and heart rate turbulence (HRT) in patients with arterial hypertension of the II-nd degree. Material and methods. We have studied the parameters of heart rate variability and turbulence in 214 persons with arterial hypertension of the II-nd degree, of them 80.8 % having ventricular arrhythmias according to the Holter monitoring. We have analyzed the correlations of the parameters with the patient’s age, average heart rate (HR), circadian index (CI), left ventricular mass index (LVMI) and left ventricular ejection fraction (LVEF). The statistical analysis of the results has been made using the analytical package «Statistica» 10.0. Results. We have revealed statistically significant correlations of the HRV parameters with the age of patients, average HR, circadian index, ejection fraction. Thus, high level of the statistical significance of the interrelation of HRV parameters has been confirmed. We have received statistically significant correlations of the HRT parameters with the left ventricular mass index (LVMI), ejection fraction, HR average, quantity ventricular extrasystoles. High level of the statistical significance of the interrelation of HRT parameters (TO and TS) has been revealed. Conclusion. The received results can be used during the selection of the group of patients with arterial hypertension having high risk for unfavorable outcomes. Taking into account the features of the heart rate variability and turbulence parameters and factors associated with them this will enable the individualization of the assessment of the risk in arterial hypertension as much as possible and prescription of adequate treatment for each patient.
